Amia Yo [d. 201 BG] was the kitchen slave of the robot Erasmus on his villa on Earth. She first met captured Serena Butler during the 'good deed feast' made by Erasmus. She befriended her, as well as little Manion. Serena told her about her thoughts of escaping and the need to see the robot's laboratory, which was forbidden for Serena. Amia agreed to lent Serena her kitchen clothes, and disguised as Amia, she left Manion with her accompanied a slave to the laboratory, in a route to feed the test 'subjects'.
